"When Nina Pham walked into the Oval Office, the President gave her a big hug as her family and White House Dr. Ronny Jackson watched. Nina, a Dallas nurse diagnosed with Ebola after caring for an infected patient in Texas, was being treated at the National Institutes of Health in nearby Bethesda, Maryland, and the President invited her to the White House when she was released after being declared Ebola-free."
